Use C-c C-l to load the file into GHCi. This is better than just compiling it:
you get an interactive environment in which to play around with, test out
functions, etc. You can still 'run' your program by typing 'main' in GHCi.

I wouldn't be surprised if this code had bit-rotted, or if there never has been
Windows support. It's a corner function, used by few and therefore not that
polished. By all means, try it out, and if it doesn't work, feel free to submit
patches, but I doubt it'll get changed any time soon by a haskell-mode developer
